' WILLIAM P.,GBAY, OF CAMPBELLTON, NEW BRUNSWICK, CANADA.

- BRUSH.

Specification of Letters Patent,

- Application filed June 13, 1916. Serial No. 103,528.

To all whom it may concern:

Be it known that I, WILLIAM P. GRAY, a subject of the King of Great Britain, residing at Campbellton, in the Province of New Brunswick, Dominion of Canada, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

This invention relates to brushes intended more particularly for use in cleaning live stock although capable of general use. The invention seekstoprovide a power driven ,brush which may be readily manipulated and applied to any surface to be cleaned and also to provide means whereby any hair or other matter or substance which may tend to cling to the cleaning surface may be readily removed therefrom. The invention also.

seeks to provide means whereby the wear upon the working parts may be taken up and also to provide a brush of simple construction which will be efficient in operation and which may be readily repaired or renewed as may be necessary.

The invention is illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of a brush embodying my present improvements;

Fig. 2 is a longitudinal central vertical section of the same;

Fig. 3 is a horizontal section on the line 33 of Fig. 2;

Fig. 4 is a transverse section on the line 44 of Fig. 2;

Fig. 5 is an enlarged horizontal section on the line 5 -5 of Fig. 2. v

In carryingout my invention I employ a frame or housing which may conveniently consist of side plates 1 connected by a back or covering plate 2 and a handle 3 may be disposed longitudinally upon the back plate 2 and secured thereto in any preferred manner. A transverse spacing bar 4. is disposed between the side plates and a stay bolt 5 is inserted through the said bar and the side plates to hold the-said plates in a fixed relation and prevent spreading of the structure. In the side plates adjacent the ends thereof I mount shafts 6 which carry rollers 7 the said rollers being constructed with annular grooves 8 near their respective ends and hav ing sprocket teeth 9 located within the said Sprocket chains 10 are trained around the rollers to run in the said grooves and engage the said sprocket teeth and power may be applied directly to one of the said shafts 6 so as to effect travel of the said chains and of the brush carried by the same. That shaft 6 to which power is applied is mounted in fixed bearings in the side plates 1, but the shaft at the opposite end of the device is provided with flat sided axial extensions 11 which are mounted in longitudinal slots 12 in the side plates so that they may be shifted longitudinally of the said plates and thereby take up the wear upon the chains or the rollers. To effect such longitudinal adjustment of the said shaft, bolts or screws 13 are fitted in the ends of the extensions 12 and are inserted through the ends of a cross bar or stay 14 which is fitted against adjacent ends of the side plates 1 as will be readily understood. It will be readily understood that if the screws 13 be threaded in theextensions 12 rotation of the screws will effect longitudinal adjustment of the said extensions and the adjacent roller 7, or if the screws be fitted loosely through the extensions and equipped with nuts 15 the turning home of the said nuts will, in a similar manner, effect longitudinal adjustment of the extensions and the roller. It will be understood, of course, that the shaft to which power is applied has the apron carrying roller secured thereto so that the rotation of the shaft will be imparted directly to the roller. vice, however, the roller is not secured to the shaft but rptate's about the same.

. The rubbing, cleaning or brushing surface may be of any desired form, but I prefer to employ a strip or apron of felt 0r At the other end of the de- Patented May 22, 1917.

similar material, as shown at 16, the said strip or apron being any length which may be preferred, the drawings illustrating the same as being somewhat shorter than the chains which carry it but it is obvious that the apron may be equal in length to the chains. The ends of the strip or apron are fitted over pins or studs 17 fixed upon some of the links of the chains so that the apron will be held taut upon the chains and will be forced to move therewith. The parts should be of such relative dimensions that the under surface of the apron will be at least flush with the edges of the side plates 1 and it will preferably project slightly beyond said edges so that it will efi'ectually engagethe surface to which it is applied.

Upon the driving shaft 6, I secure a gear wheel .18 which meshes with an idler 19 mounted on the side plate 1 and the said idler in turn meshes with a pinion fixed upon the shaft 21 of a beater 22 which is disposed between the side plates above the brushing apron 16 and is provided with a plurality of longitudinal blades 23 which are adapted to strike upon the surface of the said apron and thereby remove from the same any hairs or other substances which may tend to cling thereto. It will be noted that the opposed adjacent surfaces of the beater and the brush will be rotating in opposite directions and, consequently, the impact of the beater blades upon the brush will efl'ectually remove all dirt and foreign matter from the same.

In order that water or other liquid may be applied to the brush when desired a nipple 2% is provided in the back plate 2 and this nipple receives the end of a hose 25 which obviously may be of any desired length and extend to any source of supply.

It is thought that the use of the device will be readily understood from the foregoing description, taken in connection with the accompanying drawings. The brush is held to the surface to be cleaned by applying pres sure through the handle 3 and the motor to which the shaft 6 is connected is then started. The rotation of the shaft 6 Will obviously set up a travel of the chains 10 and the apron 16 carried by the same so that said apron will be moved vigorously over the surface to which it is applied and as each portion of said surface is cleaned the brush may be quickly and easily shifted to another portion by means of the handle 3. By suitably adjusting the bolts or screws 13 the tension of the chains 10 and the apron 16 may be easily regulated and wear upon any of the parts taken up. When the apron be comes worn to such an extent as to be unfit for further use it may be quickly and easily removed from the chains and a new apron substituted therefor and this operation may be performed without disassembling any of the parts inasmuch as it is only necessary to move the apron until the pins 17 appear at the bottom of the device whereupon the ends of the apron may be quickly lifted off said plus. 4

My device is exceedingly simple in the construction and arrangement of its parts and may be produced at a very low cost. It is very light and may be manipulated for a considerable period of time without causing any fatigue to the user.

Having thus described the invention, what is claimed as new is:

A brush comprising a frame, a rubbing apron mounted for travel within the same, a heater disposed within the frame to bear upon the said apron, and means for causing the opposed adjacent surfaces of the heater and the apron to travel in opposite directions.

In testimony whereof I afix my signature. I
